WIRE-COILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 296,806, dated April l5, 1884.

Application led September 4, 1883. (No model.)

To alt whom, it may concern:

Be it known that I, LA. FAYYETTE VILDER- MUTE, of Columbus, county of Franklin, State of Ohio, have invented a new and useful Improvement in llfire-Coiling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this speciication, in which Figure l is a perspective view oi a wirecciling machine with my improvements attached. Fig. 2 is a vertical section of the same. Fig. 3 is a separate view of the twisted bit. Fig. a is a separate view ofthe cam-slide which operates the top plate. Fig. 5 is a detached view of the top block of the former. Fig. 6 is a detached view oi' the spring or of the forms, dic. Figs. 7, 8, 9, and l0 illustrate the manner of forming the bends between the coiled springs.

My inventionhas reference to machines for ceiling wire springs, and is an improvement on my Patent No. 245,683, issued to me August 16, 1881; and it consists in theseveral combinations oi devices, hereinafter explained and claimed. n

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the drawings, A represents a hollow post,v made in two sections and united together. Near the top of the post A is placed the mandrel B, constructed and operated by the crank B', as described in my former patent. On the top cf the post A, I secure the plate c, grooved on its periphery, and slotted on its upper face, as shown in Fig. 3. On the upper face of this plate I also provide two -vertical pins, b, of unequal diameters, around which eyes or loops of different sizes may be easily formed in the wire. per end of a twisted bit, G, which extends down in the hollow post and passes through the cam-slide c, which is caused to rise and fall vertically, and consequently causes the top plate, c, to make a revolution each time' the cam-slide passes up er down, reversing the direction oi the plates revolution as you reverse the direction of the cam-slide. `By the motion thus given to the plate a, provided with the groove a', (see Figs. 7, 8, 9, 10,) it

The top plate, c, is secured to the up! is evident that bends or eyes can be readily formed in the wire-connections betweenthe coiled springs, as shown in Fig. G. The rectangular lugs c of the cam-slide iit in the vertical slots D in the post A, and these slots act as guides to keep the slide level and force it to travel vertically, which consequently forces the twisted bit G and plate c to revolve, as before described. The cam-slide is attached byrods d or by any other convenient and suitable means to the treadle-lever E, so that when the treadle-lever is forced down it carries down also the cam-slide and causes a revolution of the plate c. lVhen the pressure is re-Y F may be made as shown in my patent before referred to. Connected with the treadle-lever by means of a rod, e, is a lever cutter-blade, G, provided with a notched cuttingedge at g, for cutting off-the wire.

. On the side of the post A, I also construct a former for pressing and finishing up the spring after it has been taken from the mandrel. vThe former consists of the stationary lower block, I-I, permanently secured to the side of the post A. From this block rise two guide-rods, 71, h, which, near their top, are bent at right angles and rigidly secured to the post. On these guide-rods slides the upper block, I, which is connected by bars t' ffl to the treadle-lever E, so that when the lever is depressed the block I may be brought down level upon the block II by means of the treadle-lever. The lower face of the upper block, I, is grooved, as shown in Fig. 5, to hold the i'oot ofthe spring so' that the block may press the spring level without being interfered with by the foot.
